The new issue of Motor Trend arrived in the mail and our eyes were instantly attracted to this story that just went live on motortrend.com. The MT crew has learned that the supercharged V8 slated for use in the next-gen Cadillac CTS-V will be none other than a "detuned" version of the 7.0L LS7 powerplant debuting in the Corvette Blue Devil, or rather, Corvette Z07. The MT editors expect the version used in the CTS-V to produce about 600 horsepower, or around 100 horses short of what the Z07 will produce.

Pick any possible competitor for the next CTS-V and it's obvious that all will come up short to Caddy's new mega muscle sedan. The BMW M3 and Audi RS4 both produce only 420 horsepower, while the horsepower happy AMG team stuffed only 503 in the Mercedes-Benz C63 AMG. Even the BMW M5, which is larger than the CTS, will come up short with an upcoming horsepower bump into the low-500 horsepower range. In short, the CTS-V will offer the same amount of horsepower as the 2008 Dodge Viper, which is pure insanity. GM's got stones, folks, and Cadillac is clearly the prime beneficiary of its newfound fortitude.

Much thanks to Motor Trend editor-in-chief Angus Mackenzie for allowing Autoblog to republish the rendering above. The July issue (you can subscribe here) is thicker than a Thesaurus and our fave in a string of recent good issues from the MT team.

      Wow I might have to seriously concider this as my next vehicle!!

      • 8 Years Ago
      Carmakers are entering dangerous political territory; the horsepower war is going to be great ammo for a lot of people.

      It's also becoming absurd to the point that I'm just tuning out to these numbers.
        • 8 Years Ago
        Good, keep tuning them out!
      • 8 Years Ago
      Here's an idea bgdc, if you don't like cadillacs then don't read blogs about cadillacs. Sounds pretty simple to me.

      And Chris, you sound so determined that you're correct yet you leave no proof. Just sounds like speculation...and not very good speculation at that.
      • 8 Years Ago
      I just don't get it. Has Cadillac looked at a gas station recently? These cars are becoming useless quite quickly, but I still want one.

      Hey AUTOBLOG i sent you a tip on this car last week and no response, anyway this car is going to be a killer. Amazing how many people on this board just dont have a clue when comes to cars.
      • 8 Years Ago
      700 hp - I can barely keep the back tires hooked up on my '06 Z06 with 505 hp. Wonder how wide those back tires will have to be...
        • 8 Years Ago
        It would be really nice to see AWD, it's a ton of horsepower!
      • 8 Years Ago
      if this car has 600hp and AWD, as some here are stating, there should be a good battle between this and the 08 Audi RS6.
      • 8 Years Ago
      This begs one question. Now that it has supercharged the LS7, what else can it do? 7L is already pretty big and englarging it more will compromise the engine.

      At least the Viper engine is NA and has more displacement. Which means when they supercharge it, it is going to whoop the Corvette.
        • 8 Years Ago
        you should know by now that the number of cylinders has hardly anything to do with the power output. It's all with displacement. 8L > 7L. Now that corvette has resorted to forced induction, what else can it do?
        • 8 Years Ago
        Lets have this conversation when Chevy "needs" a V10 to compete with the Viper.

      blitzkrieg- "it looks too blocky and not aerodynamic"
      just so you are aware, blocky IS aerodynamic. Most people think fluid and smooth means aerodynamic...take a look at a NASCAR, it is a brick made to look shapely...this is from experience as a designer and being in a wind tunnel running aero tests...

      Mike Ishi @ Jun 9th 2007 2:31AM
      @ car designer: Oh, so that's why planes are designed as cubes?

      36 blitzkrieg79 @ Jun 4th 2007 5:02PM
      Look at all the fastest cars in the world, most of them has fluid, rounded shapes

      37 Car Designer @ Jun 5th 2007 8:26AM
      trust me when I tell you that blocky IS more aero friendly


      The most aerodynamic shape is very close to a raindrop, which is not at all "blocky," there isn't even 1 straight surface on the theoretically-perfect raindrop. With only surface tension to hold the molecules of water together but the fact that the rainwater is a liquid (fluid) not solid, the molecules are free to rotate around one another to take the PATH OF LEAST RESISTANCE; the shape that gives it the least resistance (least drag) is a teardrop shape.
      I repeat, a TEARDROP shape, not a "flying brick" like NASCAR. And that's part of why Le Mans style cars have a lot of teardrop shapes and go MUCH, MUCH FASTER THAN NASCAR with about the same (800) BHP:

      GT-P cars were doing over 240 mph w/only about 800 bhp over a decade ago, which is faster than nascar's "flying bricks" with approx the same hp. 245 mph like a GT-P car causes about 45% more drag, if you keep the car the same and only change speed down to the nascar-like, pitifully-slow 200 mph... i.e. although it's only a few extra mph from 200-245, it's a HUGE difference in drag.
      ----->NOTE: Unlike a GT-P car, nascar's shapes are blocky NOT because they were the best in windtunnels, as "car designer" seems to suggest, but because the NASCAR REGS call for each car to resemble the cheap and practical cars each automaker sells to the typical nascar fan, what the fans drive on the street. Look at a GT-P or even LMP car, then look at the Dodge or Chevy nascars: The nascar racing car looks a lot more like an ACTUAL CHEVY OR DODGE MAKE/MODEL that you can buy at your local dealer, whereas an LMP or GT-P car looks nothing like a practical, stock roadcar...and that is on purpose: The largest surfaces of a car's body in nascar cannot be modified or replaced for better aero than, oh, your average crapped-out $20k car's aero, so the aero improvements are minimal, and this is because, as Nascar itself even says... A reason for nascar's popularity is that Joe Sixpack can think his car is like a nascar racing car, and although Nascar modifies nearly everything INSIDE each car which makes Joe Sixpack very WRONG to think his showroom-stock car is anything like the professional-racing series nascar cars.... The goal of nascar regs is to keep the exterior -- including most aerodynamics -- close to a showroom car so that the automakers who put money into the nascar series can make Joe Sixpack FEEL like his $20k showroom-stock car is "sorta like a nascar Busch/etc. series car" which encourages him to buy the showroom car, and that's because Joe Sixpack doesn't see or understand the differences under the skin, and what is unseen isn't understood by the average layperson: eg. a non-engineer/non-mechanic.

      Unlike nascar, GT-P cars had UNLIMITED mods to aerodynamics...and with these TEARDROP shapes typical of GT-P, which are superior to nascar's blockiness, Toyota started its Lexus division -- producing cars with lower drag-coefficients than ANY automaker involved in nascar, just after their GT-P learning experiences. Let's let that fact sink in, and speak for itself as a great example that "blockiness like nascar is NOT good aero design". ;-)
      ...Basically, automakers whose main high-speed circuit experience is in nascar aren't learning much and applying it to their roadcars -- because you cannot get as much aero expertise from your racing program when it's as LIMITED mods as nascar's pro racing programs.

      But, for best OVERALL performance ("overall" meaning "aside from just reducing drag"... eg. to get downforce [or lift, for planes...], eg. to fit 4 tires at the corners for great cornering [on cars only, not planes obviously], and eg. to fit all the other parts a car or plane needs, and WHERE those parts need to be in relation to one another...) because of all these items aside from reducing drag, of course most cars (and planes) aren't actually designed like one big teardrop. You'll get the teardrop-shaped roofs/"greenhouses" in GT cars (i.e. the parts of the car above the base-of-the-windshield), and even cars purpose-built for the Utah salt flats aren't exactly

      Here is a podcast I found talking about it. It sounds like this is certain to be a huge hit.

      Yeah, all this horsepower is pretty crazy. I'm definitely enjoying it, but while this much horsepower in a supercar is to be expected: Enzo, Murcielago, Koenigsegg, MC12, Zonda, etc. I would say "not so much" in a small sized sedan. I think the M5 is already pushing the limit at 500 HP for a mid-sized sedan. True to GM history and obviously Corvette history, this CTS-v is sure to be tricky to keep those wheel planted on the road. And I cant imagine a sedan of this size (including 3 series, A4, C-class, etc) really being able to fully utilize all this power when it comes to handling the turns. I surely wouldn't take this car on the track and expect to be a dominating force, but I would definitely be manuvering quickly down the highway and not so busy surface streets, and look pretty damn sexy doing it. Wonder if I could outrun police in a chase - hmmm.
